Data were obtained on the dynamics of the abundance of the biocontrol strains of Pseudomonas chlororaphis SPB1217 and Pseudomonas fluorescens SPB2137 with antifungal activity. These strains are able to develop in the rhizosphere of cucumbers grown on mineral substrate under hydroponic conditions in industrial greenhouses. After four weeks of vegetation of plants, the abundance of the inoculated strains was 19-28% of the total bacterial numbers determined by inoculation onto solid medium. The investigated strains spread together with the young, actively growing and exudating roots; they reached a stable level of abundance in deep layers of the greenhouse substrate. A significant difference in the abundance of fungi in the tested variants was observed after 20 days of vegetation: the abundance of fungi in the control was two times higher than in the variant inoculated with strain SPB2137.
获得了具有抗真菌活性的绿针假单胞菌SPB1217和荧光假单胞菌SPB2137生物防治菌株数量动态的数据。这些菌株能够在工业温室水培条件下生长在矿物基质上的黄瓜根际中生长。植物生长四周后，接种菌株的数量占接种到固体培养基上测定的细菌总数的19 - 28%。所研究的菌株与幼嫩、活跃生长和分泌物质的根一起扩散；它们在温室基质深层达到了稳定的数量水平。在植物生长20天后，观察到测试变体中真菌数量存在显著差异：对照中真菌数量比接种菌株SPB2137的变体高两倍。
